[alsa-devel] [PATCH v4 0/3]ASoC: cygnus: Add audio support for Broadcom Cygnus SoC
by Simran Rai 02 Dec '15

02 Dec '15

Hi, This patchset contains audio support for Broadcom's Cygnus SoC. It contains DT bindings and core audio driver. The audio driver supports both capture and playback of Audio PCM samples over I2S/TDM interface and provides playback support over SPDIF interface. This patchset is derived from a previously submitted patchset: http://lkml.iu.edu/hypermail/linux/kernel/1503.3/05434.html This patchset has been tested on Cygnus wireless audio bcm958305K board. It is based on v4.3-rc5 and is available from github: repo: https://github.com/Broadcom/cygnus-linux/tree/cygnus-sound-v4 Changes from v3: - Fix the subject lines to match the style for the subsystem Simran Rai (3): ASoC: cygnus: Add DT bindings for Broadcom Cygnus audio ASoC: cygnus: Add Cygnus audio DAI driver ASoC: cygnus: Add Cygnus audio DMA driver .../bindings/sound/brcm,cygnus-audio.txt | 54 + sound/soc/bcm/Kconfig | 9 + sound/soc/bcm/Makefile | 5 + sound/soc/bcm/cygnus-pcm.c | 859 +++++++++++ sound/soc/bcm/cygnus-ssp.c | 1508 ++++++++++++++++++++ sound/soc/bcm/cygnus-ssp.h | 129 ++ 6 files changed, 2564 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/brcm,cygnus-audio.txt create mode 100644 sound/soc/bcm/cygnus-pcm.c create mode 100644 sound/soc/bcm/cygnus-ssp.c create mode 100644 sound/soc/bcm/cygnus-ssp.h -- 1.7.9.5

[alsa-devel] [PATCH] ASoC: dapm: Replace siggen widget type with mic widgets
by Charles Keepax 02 Dec '15

02 Dec '15

The siggen widget type doesn't really require its own special handling. It can be handled identically to a mic widget, ie. it is a source of a signal and causes things to power up when an output is connected. Additionally, several places (cs42l52, cs42l56, wm8962, arizona_haptics) tie siggens in to the input framework and the pattern for this is usually to use snd_soc_dapm_enable_pin/disable_pin on the siggen widget. However, as siggen widgets present as always on (the power check always returns 1), this leads to some odd interactions with DAPM. Enabling/disabling the widget then connecting it to a path works as expected, however once in a path enabling the widget has no effect. dapm_widget_set_power will return immediately as the current power state of the widget will return 1, meaning we never check peer power states. Treating the widget as a mic widget causes the expected behaviour in all cases. This does cause a minor cosmetic side effect that siggen widgets no longer show as always on through debugfs, although in the case described above that is more representive of their behaviour.

[alsa-devel] snd-fireworks requires larger period sizes than FFADO
by Dominic Sacré 02 Dec '15

02 Dec '15

Hi, I'm trying to use an Echo AudioFire 4 with the snd-fireworks driver. With FFADO the device works reasonably well at a period size of 64 samples (on a PREEMPT_RT kernel), whereas with snd-fireworks the lowest possible period size seems to be 256 samples. This is what JACK says when I try to start it with a period size of 128 samples: configuring for 48000Hz, period = 128 frames (2.7 ms), buffer = 2 periods ALSA: final selected sample format for capture: 32bit integer little-endian ALSA: cannot set period size to 128 frames for capture The lowest achievable analog roundtrip latency seems to be around 19ms (at 2x256 frames), as opposed to 8.3ms with FFADO (at 2x64). Are there any known limitations of the snd-fireworks driver in this regard? Thanks, Dominic

Hi Mark These patch-set adds TDM Extend Mode to Renesas R-Car sound driver. 1) - 9) tidyup / cleanup patches 10) - 14) TDM Extend Mode support Unfortunately, our board can't use this TDM Extend Mode, because our SoC and codec are using different style TDM.

[alsa-devel] [PATCH] ASoC: arizona: Add 32uS delay after putting FLL into freerun
by Charles Keepax 01 Dec '15

01 Dec '15

When switching between two clock sources using the FLL freerun to smooth the transition we should wait 32uS after putting the FLL into freerun before we proceed. In practice we appear to be getting enough delay from the surrounding code, but better to make it explicit.
